Prize motivation: “for their discoveries concerning magnetic resonance imaging”
Prize share: 1/2
Work
Protons and neutrons in the atomic nucleus behave like small spinning magnets. Accordingly, atoms and molecules assume a certain orientation in a magnetic field. This can be dislodged, however, by radio waves of certain frequencies that are characteristic for different atoms. By developing calculation methods during the 1970s, Peter Mansfield contributed to use of the phenomenon to create images of the human body’s interior. The incidence of hydrogen atoms is measured and differences in the water content of different tissues provides a basis for magnetic resonance imaging.
Play a game!
In the MRI imaging technique, strong magnets and radio waves are used for getting images of inner organs made of soft tissue. In this game you are to assist during an MRI investigation. Good luck!
Nobel Prizes and laureates
